I am getting this when I tried to simulate this non-linear study

 

Solution failure in a Step>1, it could be due to:  The solution may be at a buckling or limit point, i.e.,  displacements grow large under constant forces. If so,

for force control or contact problems, this is the end of solution (check out the response graphs).

The solver numerical difficulties:

1. Reduce the Singularity-elimination-factor (.5 or 0.)

2. For Plasticity models, raise ETAN >Ex/100.

3. For Nitinol, or large strain plasticity, set:

    Maximum-Strain-Inc.=(or >)1. (0.01 defaults to 1.)
